I mean like...

Also, I get that they get targeted for bullying if they don't listen but like how is the faculty and staff allowing this? Can't literally anyone contact the police or switch schools this just seems so strange I don't GET IT

i really recommend to read it a second time! the first time i read it, i thought it was just some weird manga, but believe me, it's a lot more. i think the school and its rules represents our modern society, how being part of a caste and how a certain surname and a certain way of living changes the way people think about us. also, (i might go deep into this theory because i really like this manga and so sorry sjjzhq also sorry for the dumb mistakes i'm sure i'll make) kids don't go call the police because, in the "real world" you can't change things, you have a role and that role will be part of you until you die, if you are at the bottom, you can't call someone that will solve all your problems. But in this reality, in this school, you have the smallest opportunity to change your status, your future, the way people see you and to become someone. this possibility is available only in the game. that's definitely some weird/toxic/abnormal way of thinking but that's what i believe goes in these guys mind. the only one who seems to not care if he has crown on his head, is azusa and later on karino but definitely for different reasons. from my point of view the whole manga talks about (society and) changes. for example, azusa is the son of a prostitute and even he seems to not accept it. he know his role /can't/ be the son of a prostitute, but the real world seems to not care, he's been treated badly, probably bullied and treated with pity (which he seems to hate). that's why finding a place where he can be the king, the place that he knows is his, seems to be perfect for him. when karino takes his place as king he becomes "karino's woman". you can find this term several times in the manga because it's the worst for azusa. he became someone's woman, he became his mother and, he isn't just some target, the reality he hated and didn't want to live, took the one he so desperately liked. around ch 3 i believe, azusa goes back home and sees his mother that tells him to go away, he thinks something along the line "where can i go? i don't have a place i belong to". being king was a place he could escape into, but now it's seems like life wants him to be a certain way, and he seems not to be able to do anything. as he goes at school (where btw karino tells him "what are you doing in this room? only the king can stay here" emphasising the idea of " a place that azusa simply can't have") karino is gentle with azusa which makes azusa noticed that that's strange, nay, different. as time passes, azusa changes, he doesn't call it "a change" but he starts to accept a life where he his someone's woman, probably believing that will be his life from now on. he doesn't do anything when karino rapes him, once karino tells him to hug him (he doesn't say hug hug but you know) and azusa doesn't even seem to care, he is about to do it when someone enters the room. he had never changed before but it's seems like he's accepting that he has a destiny that he can't escape. changes are a big thing for him, but at the same time, he asks himself if karino can change too. if that does happen, it means the game can change, if that happen it means that the "real world" can change too, that means there is no inescapable destiny.
but karino doesn't "simply change". for example, when azusa goes to his haus, karino tells him that his real life isn't the game, that school is in fact just a game and that he's just waiting to get into the real world, meaning for azusa that there is in fact a destiny he can't escape from. as azusa goes back home he sees his mom and karino with his father on tv. he says something like "i know you'll come back to the real world" which puts azusa in a weird mentality. he still puts his future on karino. since he can't change the game, he decides that he will ruin karino's real life, putting him below azusa. that will not make him king, but the mentality he had at the beginning (knowing that he isn't at the bottom of the piramidy). he doesn't want to change, he wants to be the king he was. later on when a classmate tells him he changed he doesn't want that because it feels like he's the only one doing so. every time karino is gentle, calm or just talk about something personal after a while he's back on being mean, rude or on raping azusa. azusa says something "i can't believe i thought he could be gentle/caring etc…" and maybe because he looks so much at him (plotting and trying to understand his weaknesses) he understands he is the only one that knows something about karino. he says something like "i'm the only one who knows this heat" in the chapter where i believe for the first time the had sex, the first time it wasn't a rape. they aren't definitely in love or some shit but still. in the 23 ch. a classmates tells azusa he did change and again, that scares him. as he's alone with karino he noticed that he (azusa) is being weird, but at the same time he can't accept that he changed. at first azusa thinks "there is something weird here, a king and a target can't have dinner or a normal conversation together" the first thing he thinks is that he is a target, which he until now didn't seem to accept. he returned at when he was accepting being "someone's woman" but something else did change this time, karino. azusa saying "we look like a couple" makes me think that there is a transformation from "someone's woman" to a "couple", from one person changing to two.
probably azusa thinks that once again, even if he seems different then usual, karino will never change and that once again he'll have to hear karino saying "i have e real life outside of this where i'm a real king, this is just a game". both changed because once again azusa is accepting the idea of being a target (kind of hating himself for that) while karino seems not to care anymore. man i don't know why i got so deep into this, i could talk about this manga for hours (as you could tell i did) one day i'm just gonna open a blog where i talk about this shit (yes my life is just THAt sa) bye so sorry

appreciate the effort it took to write this. Interesting perspective. I guess since it's so far detached from reality my brain can't make any sense of it. But I guess it's a work of fiction regardless. Thank you again
